Notes from the work.
Engineering lessons, research notes, tutorials and opinions. I publish here only when a piece is finished.
The first notes are on the way.
Topics in the queue: what moved a tool-calling eval from 19/26 to 24/26, how a rollback-safe production cutover is structured, and how to audit an API across endpoints and roles. In the meantime, the lab has results and failures from real builds.
